[jdbc-v2] Statement that not detected has no result set.

[chernser]

Description

Statement like SELECT number, FROM system.numbers LIMIT 1 is not recognized by parser but valid.
In this case no result set is returned.

Expected behavior:

• when parser fails to parse statement but it passed to server and no error occurs result set should be returned
• when result set for unknown statement type is missing and executeQuery() called then exception should be throws according to the JDBC
• when result set for unknown statement type is missing and execute() is called then false should be returned indicating that result set is missing.
